lzlib/ChangeLog

2011-10-25  Antonio Diaz Diaz  <ant_diaz@teleline.es>

	* Version 1.2 released.
	* encoder.h (Lee_update_prices): Update high length symbol prices
	  independently of the value of `pos_state'. This gives better
	  compression for large values of `--match-length' without being
	  slower.
	* encoder.h encoder.cc: Optimize pair price calculations. This
	  reduces compression time for large values of `--match-length'
	  by up to 6%.
	* main.cc: Added new option `-F, --recompress'.
	* Makefile.in: `make install' no more tries to run
	  `/sbin/ldconfig' on systems lacking it.

2011-01-03  Antonio Diaz Diaz  <ant_diaz@teleline.es>

	* Version 1.1 released.
	* Compression time has been reduced by 2%.
	* All declarations not belonging to the API have been
	  encapsulated in the namespace `Lzlib'.
	* testsuite: `test1' renamed to `test.txt'. Added new tests.
	* Match length limits set by options -1 to -9 of minilzip have
	  been changed to match those of lzip 1.11.
	* main.cc: Set stdin/stdout in binary mode on OS2.
	* bbexample.cc: New file containing example functions for
	  buffer-to-buffer compression/decompression.

2010-05-08  Antonio Diaz Diaz  <ant_diaz@teleline.es>

	* Version 1.0 released.
	* Added new function LZ_decompress_member_finished.
	* Added new function LZ_decompress_member_version.
	* Added new function LZ_decompress_dictionary_size.
	* Added new function LZ_decompress_data_crc.
	* Variables declared `extern' have been encapsulated in a
	  namespace.
	* main.cc: Fixed warning about fchown's return value being ignored.
	* decoder.h: Input_buffer integrated in Range_decoder.

2010-02-10  Antonio Diaz Diaz  <ant_diaz@teleline.es>

	* Version 0.9 released.
	* Compression time has been reduced by 8%.
	* main.cc: New constant `o_binary'.

2010-01-17  Antonio Diaz Diaz  <ant_diaz@teleline.es>

	* Version 0.8 released.
	* Added new function LZ_decompress_reset.
	* Added new function LZ_decompress_sync_to_member.
	* Added new function LZ_decompress_write_size.
	* Added new function LZ_strerror.
	* lzlib.h: API change. Replaced `enum' with functions for values
	  of dictionary size limits to make interface names consistent.
	* lzlib.h: API change. `LZ_errno' replaced with `LZ_Errno'.
	* lzlib.h: API change. Replaced `void *' with `struct LZ_Encoder *'
	  and `struct LZ_Decoder *' to make interface type safe.
	* decoder.cc: Truncated member trailer is now correctly detected.
	* encoder.cc: Matchfinder::reset now also clears at_stream_end_,
	  allowing LZ_compress_restart_member to restart a finished stream.
	* lzlib.cc: Accept only query or close operations after a fatal
	  error has occurred.
	* Shared version of lzlib is no more built by default.
	* testsuite/check.sh: Use `test1' instead of `COPYING' for testing.

2009-10-20  Antonio Diaz Diaz  <ant_diaz@teleline.es>

	* Version 0.7 released.
	* Compression time has been reduced by 4%.
	* testsuite/check.sh: Removed -9 to run in less than 256MiB of RAM.
